I have signed the petition and, on request submitted the following official motivation:

Academic philosophy has a gender problem and has had one for a long time. If nothing else, this becomes obvious when philosophy is compared to other academic areas when it comes to representation at higher levels of professional status and controlled for results in studies. Besides the general political spin that can be made on this with regard to gender equality, I find this situation troublesome also for purely academic and philosophically chauvinistic reasons; our beloved subject misses a large portion of potential talent due to what mainly seems to be structural reasons.The proposed action in this petition in order to influence conference organizers when it comes to keynote speakers is, in light of this, a very modest one.
